Summary
Opiophobia, the fear of opioids, lacks clear definition and measurement, leading to inconsistent research and interventions. This review highlights the need for standardized definitions and validated instruments to improve pain management strategies.
Area of Science:
- Pain Management
- Medical Sociology
- Health Psychology
Background:
- "Opiophobia" is a term used to describe the underutilization of opioids, but it lacks a clear definition and consistent measurement.
- This ambiguity complicates research and clinical interventions in pain management.
Purpose of the Study:
- To systematically review the conceptualization and operationalization of opiophobia in quantitative studies involving adult populations.
- To evaluate how opiophobia is defined and measured across diverse healthcare contexts.
Main Methods:
- A systematic review of peer-reviewed articles published before July 2024 from CINAHL, Embase, MEDLINE, and Scopus databases.
- Included studies defined and/or measured opiophobia or opioid stigma in adult patients, caregivers, and healthcare professionals.
- Two-phase review: first, study characteristics; second, conceptualization and measurement of opiophobia.
Main Results:
- Thirty-six articles met inclusion criteria, with a focus on healthcare professionals (64%) and adult patients (33%).
- Common definitions of opiophobia included fear, prejudice, reluctance, addiction, exaggeration, underutilization, and inappropriate attitudes.
- Limitations included a predominance of observational designs (89%) and the use of investigator-developed instruments (73%).
Conclusions:
- Current instruments measuring opiophobia primarily focus on opioid-related fears and resulting behaviors.
- It remains unclear if opiophobia encompasses poor adherence to prescribed opioids.
- Variations in definitions and measurement tools create inconsistencies, necessitating further research for standardized interventions.

210
Obsessive-compulsive disorder (OCD) is a mental health condition characterized by recurrent obsessions, compulsions, or both, which consume significant time and interfere with daily functioning. Obsessions involve persistent, intrusive, and unwanted thoughts, images, or urges that evoke anxiety. Common examples include irrational fears of contamination or harm. Compulsions are repetitive behaviors or mental acts performed to reduce the anxiety caused by obsessions. For instance, individuals...

01:09Preparedness and Phobias
152
Human fear responses to certain stimuli, such as darkness, heights, deep water, and blood, can often arise despite the absence of direct negative experiences. This phenomenon is rooted in evolutionary psychology, which posits that humans have developed a predisposition to fear stimuli that historically posed significant survival threats. This predisposition, known as preparedness, suggests that early humans who developed a fear of potentially dangerous entities, such as venomous snakes and...

01:25Analgesia and Pain Management
803
Pain is critical to various clinical pathologies, provoking an urgent need for effective management. Pain, whether acute or chronic, is a complex neurochemical process. Its alleviation depends on the type, with nonopioid analgesics effective for mild to moderate pain, such as musculoskeletal or inflammatory pain, while neuropathic pain responds best to anticonvulsants, tricyclic antidepressants, or serotonin/norepinephrine reuptake inhibitors. For severe acute or chronic pain, opioids may be...

01:18Anxiety: Overview
350
Anxiety is a common mental disorder featuring excessive worry, fear, and apprehension, significantly affecting daily life. People with anxiety disorders experience persistent and intense anxiety, interrupting their everyday functioning.
Individuals with anxiety often experience a range of physical and emotional symptoms, including sweating, trembling, tachycardia, and disturbances in sleep patterns. These symptoms vary in intensity and frequency but are generally disruptive and distressing.

01:22Opioid Receptors: Overview
1.8K
Opioid receptors, including the mu (μ, MOR), delta (δ, DOR), and kappa (κ, KOR) types, belong to the rhodopsin family of G protein-coupled receptors. These receptors are located throughout the central and peripheral nervous systems and in non-neuronal tissues such as macrophages and astrocytes. Opioid receptor ligands can be categorized into agonists or antagonists. Highly selective agonists include [d-Ala2, MePhe4, Gly(ol)5]-enkephalin or DAMGO for MOR, [D-Pen2,...

01:15Opioid Analgesics: Synthetic and Semisynthetic Opioids
437
Synthetic and semisynthetic opioids are pivotal in pain management and tackling opioid addiction. Semisynthetic opioids, including morphinans (morphine derivatives), oxycodone, oxymorphone, hydrocodone, and hydromorphone, have improved pharmacokinetic profiles compared to morphine. Additionally, heroin and 6-MAM (6-Monoacetylmorphine) show better CNS penetration than morphine due to heightened lipid solubility. Hydromorphone, a potent opioid, undergoes hepatic metabolism to form the active...
